Recent results for Galactic and Magellanic Cloud Wolf-Rayet stars are\nsummarised based on line blanketed, clumped model atmospheres together with UV,\noptical and IR spectroscopy. The trend towards earlier WN and WC spectral types\nwith decreasing metallicity is explained via the sensitivity of classification\ndiagnostics to abundance/wind density, such that WR mass-loss rates are\nmetallicity dependent. Pre-supernovae masses for WC stars are determined, in\nreasonable agreement with CO-cores of recent Type-Ic SN.\n
